After applying force or otherwise altering the tori with an external program you need to also move a joint on that very frame, otherwise Toribash doesn't save it (Toribash only records what happens on frames where a change was made, the rest is simulated with the ingame physics).
For example a 20 tf multiplayer match only has information saved every 20 frames if you look at it in a text editor.
So to solve the choppyness you need to alter a joint on any frame you use the script, this is to cut down .rpl file sizes and will be different in Next

Also I don't mean to piss on your bonfire chris because this is a great script but there is also Ingame Hack.lua by NutHug which I think is more user-friendly, at the cost of not being able to add DMs

I'm working on updating this with the new UI system that sir and the lua team have supplied, so expect an update within a few weeks! Thank you for the feedback.
